MgF2 mea'ai
Fa'amatalaga
MgF2 o loʻo faʻaaogaina e fai ma tioata, prism ma faʻamalama mo le galu umi mai le 110nm i le 7.5μm.O se mea e sili ona talafeagai e fai ma faʻamalama mo ArF Excimer Laser, mo le mafuaʻaga o lona faʻasalalauga lelei i le 193nm.E aoga foi e pei o se polarizing opitika i le itulagi ultraviolet.

MgF2 Substrate Fa'amatalaga
MgF2 mea'ai e fa'atatau i se mea fa'apipi'i e faia i le mea fa'amea tioata magnesium fluoride (MgF2).O le MgF2 o se mea faʻapipiʻi faʻapitoa e aofia ai elemene (Mg) ma le fluorine (F).
MgF2 substrates o loʻo i ai le tele o mea faʻapitoa e faʻaalia ai i latou i le tele o faʻaoga, aemaise lava i le fanua o mata ma le faʻapipiʻiina o ata manifinifi:
1. Malamalama maualuga: MgF2 e sili ona manino i le ultraviolet (UV), vaʻaia ma infrared (IR) itulagi o le fusi eletise eletise.O loʻo i ai le lautele o fesoʻotaʻiga mai le ultraviolet ile 115 nm i le infrared ile 7,500 nm.
2. Low index of refraction: MgF2 o loʻo i ai se faʻailoga maualalo o le refraction, lea e avea ai ma mea lelei mo AR coatings ma optics, aua e faʻaitiitia ai mafaufauga le manaʻomia ma faʻaleleia le moli.
3. Maualalo absorption: MgF2 fa'aalia maualalo absorption i le ultraviolet ma itulagi spectral vaaia.O lenei meatotino e fa'aoga ai i fa'aoga e mana'omia ai le manino maualuga, e pei o tioata, prisms, ma fa'amalama mo ultraviolet po'o fa'alava va'aia.
4. Faʻamautu vailaʻau: MgF2 o loʻo faʻamautu faʻamalosi, faʻasaʻo i le tele o vailaʻau, ma faʻatumauina ana mea faʻapitoa ma faaletino i lalo o le tele o tulaga tau le siosiomaga.
5. Faʻamautu vevela: MgF2 e maualuga lona faʻafefeteina ma e mafai ona tatalia le maualuga o le vevela o galuega e aunoa ma se faʻaleagaina tele.
MgF2 substrates e masani ona faʻaaogaina i faʻaofuofu mata, faiga faʻapipiʻi ata manifinifi, ma faʻamalama mata poʻo tioata i masini ma faiga eseese.E mafai fo'i ona avea ma fa'apalapala pa'u po'o fa'ata'ita'iga mo le fa'atupuina o isi ata manifinifi, e pei o mea semiconductor po'o pa'u u'amea.
O nei mea e masani ona gaosia i le fa'aogaina o auala e pei o le fa'afu o le ausa po'o le felauaiga ausa fa'aletino, lea e teu ai mea MgF2 i luga o se mea fa'apipi'i talafeagai pe fa'atupuina e pei o se tioata e tasi.Faʻalagolago i manaʻoga faʻaoga, e mafai ona i ai substrates i foliga o wafers, ipu, poʻo foliga masani.
